SAFETY RAZOR.

Application filed March 2 2, 1927. Serial No. 177,402.

This invention relates to an improvement in safety razors wherein thehandle portionis made up of two sections adapted for relative slidingcooperation to permit the parts 5 to be arranged in compact, completelyprotected condition when not in use, with sa1d handle parts arranged forpivotal or swinging cooperation when extended to per-mit the razor'to behandle in a manner corresponding to the old type of razor.

An important object of the present invention is the provision of ahandle part in which a combined blade holder and guard is slidably andremovably mounted, the guard being adapted to form a more or lesspermanent part of the blade holder and being held in its relation to theblade by the handle part, the latter being formedto permit aparticularplay of the guardv relative to the blade when the blade is beingsharpened or honed, and a further and particular play of the guardrelative to the blade when the latter is being used for shaving. Theinvention is illustrated in the accompanying drawings in which:

Figure 1 is a view in side elevation of the improved razor, the handleparts being shown extended and adapted for relative pivotal or swingingmovement in the use of the razor for shaving orhoning purposes. Figure 2is a similar view, the handle parts being collapsed in the positionsoccupied when the razor is not in use. Figure 3 is an enlarged brokenelevation, showing particularly the means for permitting differentmovements of the guard relative to the blade as desired in the shavingor honing use of the razor.

blade, so that such may be re adi old type of razor. The housing section1 of the handle is a metallic strip of inverted U- .form, asvat 3,having the'side walls extend- .ed from a point about substantiallymidlength the section toward the bar' section connected end to providelips 4, the latter converging downwardly to provide an outlet 5 ofsomewhat less transverse dimensions than the normal similar dimensionsof the housing proper.

- The lower edges of the lips 4 incline upwardly toward the barconnected end of the section, as at 6, for a purpose which will laterappear. The walls of the housing section defining the U-shaped form arelongitudinally slotteljl, as at 7, the slots being closed at their respctive ends and terminating immediately adjacent the bar sectionconnected end of the housing section. V I a The bar section of thehandle comprises a bar-like rear end 8 formed with an opening 9 toreceive a headed pivot pin 10 which slidablycooperates with the slots 7in the That portion of the bar 8 in rear of the pivot pin 10 has itssides rear-. wardly convergent, as at 11, "to provide a substantiallywedge portion and the upper surface of this bar portion 8*may,'ifdesired, be slightly concaved, as at 12, throughout the length in rearof the pivot pin 10. In.

advance of the bar portion 8, the bar section of the handle is ofinverted U-form, as at 13,

having adimension to more or less'snugly fit within the U-form portion 3of the housing sectlon.

A blade holder 14 is designed to fit snugly within and be frictionallyheld by the U- form end 13 of the bar section of the handle. i

This blade holder is, of course, formed in a manner to receive andsecurely hold a. razor blade 15 in order that the same may rojectlaterally of the bar section-of the andle.

In this connection, it is to be understood that the blade holder may beformed in any appropriate manner to cooperate with and hold theparticular blade for which the I razor may be desi nod, and it is to beunderstood that the lade holder-here shown is merely a conventionalillustration of any structure designe'dparticularly for holding aspecial type orwell known ty 'e of razor in the holder when desired.

Secured to and carried by the holder 14 is y replaced 'otally mounted inthe respective ends of the tion, the guard is, of course, held by theside walls ofthe bar section in direct line with the blade and,therefore, acts as a complete protector for the edge of the blade.

- is too great.

It is apparent that a limited movement must be permitted the guardrelative to the blade in order to permit a shaving operation of theblade and that the guard must also be permitted a limited movementrelative to the blade when the bladeis being honed or sharpened.Experience has demonstrated, however, that if the movement permitted theguardrelative to the blade necessary forthe shaving operation ispermitted the guard during the honing operation, there will be atendency to round the edge of the blade due to the fact that themovement permitted the latter with respect to the hone or stropTherefore, the present invention makes provision for two distinctpermissible move-' ments of the guard relative to the blade, one

when the razor is being used for shaving purposes and another when therazor blade is being honed or sharpened. Obviously,

when the guard is confined between the outer walls of the U-portiOn ofthe bar section 2,

the guard is held against practically any movement relative to theblade, and therefore to provide for the desired movements of the guard,the free'edges ofthe walls of the U-shaped portion of the bar section 2are rovided with notches 19 and 20, the former eing of greater heightthan the latter.

The notches 19. which are, of course, disposed apart a distance. tosimultaneously cooperate with the side bars 16 of the guard are ofgreater height vertically of the side bars of the U-portion 13 than arethe notches 20. Therefore, when the blade holder-14 has been movedlongitudinally of the bar section to arrange the side bars 16 of theguard in alignment with the notches 19, the cross-bar '17 of-the guardis permitted a nec-' essary play relative to the edge'of the blade aswill permit a proper shaving operation of the blade without liability ofcutting the face. When the blade holder has been moved, however, to aposition to align the side bars 16' of the guard with the notches 20, asomewhat less play is pe'rmitted the andt cross-bar 17 of the guardrelative to the edge of the razor blade. This latter play is such,however, as is suflicient to permit av sharpening or honing action ofthe blade without permitting such angular relationof tldile blade andhone as will tend to round the e ge.

The razor, when not in use, is arranged as shown in Figure 2 in whichthe bar section 2 is disposed wholly within the housing sec-- tion 1.'In this position of the parts, the extended lips 4 of the housingsection snugly embrace the guard and blade and prevent any relativemovements of the parts and maintain the guard in position to hold theedge of the blade inaccessible for cutting.

When desired for use, the bar section is through the cooperation of thepivot pin 10 e slots 7. During this movement, the

extended end or bar portion 8 of, the handle section 2 bears against theupper wall of the housing section and prevents any pivotal movement ofthe bar section 2. When the pivot pin has reached the ends of the slots7, the bar section 2 maybe turned into the position indicated inFigure 1. In this movement, the wedge-shaped end. 11 of the bar section2 is forced betweenthe converging lips 4 of the housing section, therebyexerting a frictional resistance to the free pivotal movement of thehandle parts and insuring that the razor will temporarily.remain in anypivotedposition in which it may be placed. 1 When in the operativeposition as illustrated in Figure 1, the bar end 8 of the handle section2 serves as the usual finger bearing for the manipulation of the razorsimilar in all respects to-this detail in the old st-ylemazor.

The improved razor, therefore, is a safety razor which-in operativeposition may be manipulated and handled as an old style razor. The partsof the improved razor are collapsible. into compact form, in which formthe guard for the blade is held in such 1 position as to absolutelyprevent any possibility of cutting action by the blade. Furthermore, therazor, in addition to permitting a shaving operation, is designed toermit a proper honing of the blade wit out change in parts on withoutremoval of the blade from the holder or handle. "This function is gainedthrough providing a means by which the guard'is permitted a lessmovement relative to the blade than when the parts are arranged forshaving, this capability of controlling the relative movement of theguard and blade being an important one as it adapts the razor for propershaving functions and also controls the position all of the blade on thehone or strop to prevent any possibility; of rounding the blade duringsuch operation.

It is to be further noted that the wedgmg cooperation between thehousing section and bar section of'the handle insures that the partswill be retained in collapsedor housed relation against accidentalopening and that when opened, the parts may be retained at desiredangular relation without liability of slipping.

It is to be understood that if desired and as illustrated moreparticularly in Figure 9,

the blade 21 may be formed at its non-sharp-' therewith, said barsection being arrangedfor pivotal'movement relative to the housingsection in'one'position of the parts, a

blade holder removably carried by the bar section, a guard carried bythe blade holder,
